The guys over at MakeZine have instructions on how to make your own Rubiks cube with dice, magnets and epoxy resin. According to Make, the original Rubiks cube was connected with magnets, and shortly after they introduced the mechanism that can still be found in Rubiks cubes today.
These Rubiks cubes made of dice actually look real cool and I am tempted to go make one my self. I will post pics if I get around to it.
